Many ways to be smart. I gave some of them below.
Not showing extra posture while speaking.
When everyone is quietly listening and paying attention, you cannot do something that will distract or distract you from doing something that represents you as annoying to everyone.
Don't try to belittle anyone with English words in a hurry.
Adhere to spelling accuracy when writing.
Don't walk across the street or look at anyone else in a way that makes the pedestrian hesitant.
. Not trying to find out someone's top secret in front of everyone.
. To think of oneself as the youngest and to represent the truth through one's acquired knowledge when given the opportunity.
Also, there are many aspects that can make you smarter, such as being truthful, wearing clean clothes, talking with a smile, not being in a funny mood about anything serious. Thanks.
